[ads on website ] this web site header ads: how to allow them with privoxy?

hi, my question is heidisql site-related, but really asks support for another software so feel free to delete it
i use latest privoxy.org but wish to allow heidisql ads in order to support it. any user has experience on how to set user.actions & c in order to allow this site to show ads in my browser while blocking others? i tried anything including settin FF to skip privoxy for this domain... with no results
